      powerpc/qe: Select QE_USB with USB_GADGET_FSL_QE · 068e8c9d
      Anton Vorontsov authored
      Boards should know when QE_USB is used, so that they can configure USB
      clocks and pins.
      
      Another option would be to add 'select QE_USB' into USB_GADGET_FSL_QE,
      but selects are evil since they don't support dependencies.
      
      While at it, also remove 'host' from the symbol description, since the
      QE_USB code is used to support the gadget driver as well.

      powerpc/85xx: Add local_irq_restore in error handling code · 870029a6
      Julia Lawall authored
      There is a call to local_irq_restore in the normal exit case, so it would
      seem that there should be one on an error return as well.
      
      The semantic patch that makes this change is as follows:
      (http://www.emn.fr/x-info/coccinelle/)
      
      // <smpl>
      @@
      expression l;
      expression E,E1,E2;

      powerpc/86xx: Update 8641hpcn dts file to match latest u-boot · 47f80a32
      Becky Bruce authored
      The newest revision of uboot reworks the memory map for this
      board to look more like the 85xx boards.  Also, some regions
      which were far larger than the actual hardware have been scaled
      back to match the board, and the imaginary second flash bank has
      been removed. Rapidio and PCI are mutually exclusive in the hardware,
      and they now are occupying the same space in the address map.
      The Rapidio node is commented out of the .dts since PCI is the
      common use case.

      Currently U-Boot doesn't fill the clock-frequency property for
      timer nodes, so for now we have to fill it manually.

      powerpc/83xx: Add USB Host/Gadget support for MPC8360E-MDS boards · c9c5e52d
      Anton Vorontsov authored
      - Update the device tree per QE USB bindings;
      - Add timer (FSL GTM) node;
      - Add gpio-controller node for BCSR13 bank (GPIOs on that bank
        are used to control the USB transceiver);
      - Set up other BCSR registers;
      - Configure the QE Par IO.
      
      The work is loosely based on Li Yang's patch[1], which was used
      to support peripheral mode only.

      powerpc: Implement GPIO driver for simple memory-mapped banks · 3d64de9c
      Anton Vorontsov authored
      The driver supports very simple GPIO controllers, that is, when a
      controller provides just a 'data' register. Such controllers may be
      found in various BCSRs (Board's FPGAs used to control board's
      switches, LEDs, chip-selects, Ethernet/USB PHY power, etc).
      
      So far we support only 1-byte GPIO banks. Support for other widths may
      be implemented when/if needed.
      
      p.s.
      To avoid "made up" compatible entries (like compatible = "simple-gpio"),
      boards must call simple_gpiochip_init() to pass the compatible string.

      powerpc/qe: Implement QE Pin Multiplexing API · 1b9e8904
      Anton Vorontsov authored
      With this API we're able to set a QE pin to the GPIO mode or a dedicated
      peripheral function.
      
      The API relies on the fact that QE gpio controllers are registered. If
      they aren't, the API won't work (gracefully though).
      
      There is one caveat though: if anybody occupied the node->data before us,
      or overwrote it, then bad things will happen. Luckily this is all in the
      platform code that we fully control, so this should never happen.
      
      I could implement more checks (for example we could create a list of
      successfully registered QE controllers, and compare the node->data in the
      qe_pin_request()), but this is unneeded if nobody is going to do silly
      things behind our back.
